Tuning Physical Properties and Chemical Reactivity of the MgO Surface by Chemical Modification with Hexafluoroacetylacetone
Magnesium oxide, MgO, has excellent physical properties and a wide range of practical applications. It is an alkaline metal oxide, meaning that it is susceptible to reactions with any acidic functional groups. This work examines the modification of the MgO film surface with 1,1,1,5,5,5-hexafluoro-2,4-pentanedione (hfacH). This investigation addresses the changes in hydrophobicity of the MgO surface upon hfacH modification by gas-phase exposure and evaluates the effect of this modification on a model atomic layer deposition system using tetrakis(dimethylamido)titanium (TDMAT) and water producing a MgO/TiO<sub>2</sub> interface.
